301C
Oxygen, Toxic & Combustible Gas Controller

The 301C Controller continuously monitors and controls toxic gases, combustible gases, and oxygen hazards. Designed for installation and operational simplicity, the 301C reduces the cost of installation and ownership.
Using an addressable RS-485 Modbus communication protocol, the 301C uses daisy chain wiring requiring only 2 pairs of wires to connect up to 96 transmitters on the 3 input channels. This simplifies installation, in turn lowering costs. The 301C’s zoning and averaging abilities significantly reduce operational and maintenance costs.
Note: Non-branded versions of this product are available upon request.
